The explanation described in the picture

Answer 2

The variable
`w` in terms of
`x` and
`y` is equal to
`(x-2y)/(2)`. So, the correct answer is the option 2).

Explanation:

The idea is to leave alone the variable
`w` on the left. Follow the procedure below:

1. Pass the term
`2y` to the right side with opposite sign:

`2w=x-2y`

2. Pass the number
`2` from left to divide to the right.

`w=(x-2y)/(2)`

Thus, the variable
`w` in terms of
`x` and
`y` is equal to
`(x-2y)/(2)`. So, the correct answer is the option 2).
